GRAIN-DRILL.

Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed December 1, 1908. Serial No. 465,586.

To all whom it may concern.

Be it known that I, WILLIAM Fn'rznn, citizen of the United States,residing at- Middletown, in the county of Butler and State of Ohio, haveinvented certain new and useful Improvements in Grain-Drills, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to an improvement in grain drills and moreparticularly to the type of grain drills utilized for planting betweengrowing rows of corn.

The present invention is an improvement upon the grain drill of thistype disclosed in my Patent No. 762,813 issued June 14, 1904 and hasforits object the provision of means for supporting the drill in such amanner that the weight thereof will not be borne by the horse and insuch a manner that the direction of movement thereof may be readily andeasily controlled.

A further object of the present invention is the provision in a drill ofthis type, of means for increasing and diminishing the distance betweenthe furrow openers, so that where the rows of corn are somewhat closertogether than under ordinary conditions, the furrow openers may beadjusted and the machine used without injuring the growing corn.

A further object of the invention is the provision in a device of thischaracter of means for lessening the distance between the outermostfurrow openers and simultaneously lessening the distance between theshafts, so that the width of the entire machine is lessened.

Other objects of the invent-ion will be apparent from the detaileddescription hereinafter when read in connection with the accompanyingdrawings forming a part hereof, wherein a preferable embodiment of theinvention is shown and wherein like numerals of reference refer tosimilar parts in the several views.

In the drawings, Figure 1 is a perspective view of my improved graindrill; Fig. 2 is a detail of one of the adjustable drag bar heads; Fig.3 is a section on line 33 of Fig. 2; Fig. 4 is a partial side elevation,and

Fig. 5 1s a detail view of the operating mechanism for the adjustabledraw bar heads.

Referring now more particularly to the drawings, A designates the frameof the machine which is supported upon carrying wheels B of any suitableconstruction. Suspended from the forward end of the frame A by suitablebrackets c are two parallel metal bars C C which extend transversely ofthe machine and the ends of which proj ect laterally beyond the carryingwheels B. Rigidly clamped in any suitable manner between the metal barsC G are a plurality of drag bar heads (Z, to which are pivotallyconnected the forward ends of drag bars D which carry furrow openers D,which may be of any well known type. Any number of the furrow openers Dmay be employed and all of such furrow openers are positioned betweenthe carrying wheels B of the machine. In addition to the furrow openersD, there are utilized, as in the construction disclosed in my priorpatent heretofore referred to two additional furrow openers E, which arepositioned just outside of the carrying wheels B. The furrow openers Eare carried by drag bars E,the forward ends of which are pivotallyconnected to drag bar heads F, which are so secured to the frame of themachine that they may be adjusted laterally thereof, when it is desiredto increase or diminish the width between the outermost furrow openers.In the preferred embodiment of the invention, the drag bar heads F areplates which fit between the metal bars G C heretofore described, theportions of said plates which lie between said bars being provided withelongated slots f therein. The draw bar heads F are secured in positionby means of bolts which pass through the metal bars G C and the slots fin the draw bar heads, from which construction it will be apparent thatwhile the draw bar heads are secured between the bars C C, the slots ftherein will permit the same to be shifted laterally of the frame of themachine. To prevent pivotal movement of the draw bar heads F about thebolts Gr, said heads are provided with shouldersf, which are adapted tolie alongside of the edges of the metal bars G C. To permit freemovement of the draw bar heads F between the bars C C, the bolts G areprovided with sleeves G which lie between the metal bars C C and in theslots f formed in the draw bar heads, said sleeves being slightlygreater in length than the thickness of the portions of the heads lyingbetween the bars C C, so that when the bolts G G are secured in place,the bars C C will not be drawn into contact with theupper and lowerfaces of the draw bar heads. Projecting forwardly from each of the drawbar heads F are a pair of ears f in which is pivotally supported in anysuitable manner the rear end of a shaft H. The drag bar heads F are alsoeach provided with a rearward extension at the sides of which are formedlaterally disposed pintles f which constitute the means of attachmentfor the drag bars E heretofore referred to. The rearward exten sions ofthe drag bar heads F are also provided on-both the upper and lowersurfaces thereof with studs f which form the means of connection for theoperating instrumentalities for the draw bar heads, as will behereinafter more particularly set forth. Only the studs upon the uppersurfaces of the rearward extensions of the draw bar heads are utilized,but such studs are provided on both the upper and lower surfaces of theheads in order that the same castings may be used on both sides of themachine.

J ournaled in suitable bearings secured to ward extensions of the drawbar heads F are links I. F romthis construction, it will be apparentthat by shifting the shaft I, the draw bar heads F will, through thelinks I be caused to either approach orrecede from each other and inconsequence the distance between the furrow openers E will be eitherincreased or diminished. It will also be ap parent that inasmuch as theshafts H are carried by the draw bar heads F they will be adjustedsimultaneously therewith, so that when it is desirable to do so thewidth of the entire machine canbe lessened to a substantial extent.

The bearing for the shaft I preferably comprises a plate K which issupported upon the upper edge of the front bar of the frame A of themachine and extends inwardly therefrom, and a plate K which restsagainst the lower edge of the front bar of the frame of the machine, theplate K being provided with a downwardly extending portion 70 which isadapted to lie against the outer surface of the front bar of the machineancl the plate K being provided with an upwardly extendingportion /cwhich is adapted to lie against the inner surface of the front bar ofthe frame of the machine. The portions 7c and 72 of the plates K and Kare provided with alined apertures therein so that both of said bearingplates can be rigidly secured to the front bar of the machine by asingle fastening bolt K The inwardly extending portions of the plates Kand K are provided with alined apertures therein in whichthe shaft Iworks and said shaft is provided with a lug 2' projecting therefromwhich rests upon the upper surface of the inwardly extending portion ofthe plate K between two lugs .2 formed thereon, said lugs serving tolimit the movement of the shaft in its bearings.

In order to relieve the draft animal of the weight of the machine, acaster wheel L is provided for supporting the forward portion thereof.The caster wheel L is provided with the usual stem Z which is journaledin two brackets M and M, one of which is rigidly secured in any suitablemanner to the front bar of the frame A of the machine and extendsforwardly therefrom, and thevother of which is rigidly secured in anydesired manner to'the metal bars C C and extends forwardly therefrom.Loosely mounted on the pintle Z of the caster wheel L intermediate thebrackets M and M is a clevis N, to which is adapted to be secured in anysuitable manner the usual swingletree. Also loosely mounted on thepintle Z of the caster wheel L intermediate the brackets M and M is asleeve N, and it will be apparent that by positioning the sleeve eitherabove or below the clevis the machine may be adapted for use inconnection with either a small or large horse.'

The frame A of the machine carries the usual hopper, seedinginstrumentalities, and raising and lowering devices for the furrowopeners, but as these parts form no-part of the present invention, it isdeemed unnecessary to herein describe the same. A footboard 0 isalsopreferably provided, which is suspended in any suitable manner fromthe rear end of the frame of the machine. It will be obvious, however,that the foot board may be dispensed with and the hopper utilized as asupport for the operator, or that a separate seat for the operator maybe provided.

While a preferred embodiment of the 'invention is illustrated in theaccompanying V V drawings, it is obvious that many minor changes may bemade to the form therein shown without departing from the spirit of theinvention.
